In 2007, L. William Zahner, CEO of A. Zahner Company of Kansas City, Missouri, collaborated with Jan Hendrix, a world-famous Dutch artist based in Mexico City, on the Art Wall of Doha in Qatar. “Jan and I became good friends,” Zahner says. Sixteen years and over 20 projects later, Hendrix spends so much time in Zahner’s shop that people might think he works there.
Hendrix is one of dozens of artists who collaborate with Zahner to create massive artwork. “We sit down with the artist and discuss how he created different things, which opens almost endless possibilities,” Zahner says. “They challenge us, and we challenge them. Big ideas come from pushing the boundaries and trying things that haven't been done before. It’s fun because everything is different; everything is new. You're always learning something you didn't know before.”
Zahner loves the window shades Hendrix designed for the Pembroke Hill School cafeteria in Kansas City, Missouri. In fact, he installed a sample in his office. “One of the first iterations is on one of my windows. We had the clients over, and they wanted to see what it looks like,” Zahner explains. “We help the artist develop the concept. He draws it all out, and we convert it to machine language. He may do 10 different iterations, and then we make a prototype so the client experiences it.”
The two 40-foot by 40-foot shades are on opposite windows of the Pembroke Hill cafeteria. Each window has two layers for a total of 6,400 square feet of 14-gauge stainless steel. The project took a team of eight people about 18 months to complete. “We were able to put up a beautiful piece of art for little more than normal sunshades,” Zahner says. “Hendrix wanted the students to feel like they are inside a leaf.” The challenge was to keep the flowing, organic pattern within rectangular panels. “It has to be strong enough to resist loading and gravity, but we can't make the structure so pronounced that it hides the art.”
The facade of the Mexican Museum in San Francisco is also approximately 40 feet tall. However, it’s also 100 feet long and wraps around the sides of the building. The façade is inspired by a topography map of the landscape from Mexico to San Francisco. It has two distinct layers for a total of 24,000 square feet of stainless steel and took 15 craftspeople 36 months to complete. Each of the 330 rectangular panels is made of four triangles folded together. “This kind of folded plate pattern leans toward Mexican or Aztec design,” says Zahner. The interior layer is different from the exterior, so the wall appears to change as pedestrians walk by. “It adds a level of complexity to the surface and makes it more interesting than a flat wall.”
Every single opening of a Hendrix creation is unique. “We help the laser manufacturers in Germany create part of the code the machine uses to cut these because they're so complex,” Zahner says. “The other thing we do is analyze each cutout shape from a budget standpoint.” Zahner’s team saves money with slight design modifications that allow for faster work. “The Pembroke windows cut very slowly while the long openings in the Mexican Museum façade cut quickly.”
Waste metal often tips as it drops away from the sheet, which triggers the laser sensors. “When the lasers have an interference, they go all the way back to the beginning of the program,” Zahner says. “You can imagine the frustration of restarting, but we conquered that.” It’s also a problem when laser cuts begin on an edge. “We want the initial cut in a place that's going to be recycled and removed, not an edge.”
Due to strength characteristics, these projects usually use stainless steel, but Zahner has also worked in zinc. “For one, we’re doing with Jan right now,” he says, “we're going to carve black anodized aluminum so that you get the offset of the reflective surface below.”
“Working with artists is different than working with an owner or a client because the artist becomes very engaged with your people,” Zahner says. “There's no change order aspect, and the relationship is much cleaner.” Some artists are so passionate that they short themselves financially. “We always want the artists to succeed, and it's a must that the artist makes money. We want to make them famous.” He couldn’t succeed without his staff. “Our craftspeople make it possible to compete anywhere in the world. We don't want our name on it unless it's perfect.”
